Fix issue with false selection detection

Browse Source 
`selection.rangeCount` will return 1 when user is typing something in a
form widget. This will consequently trigger unvoluntary scrolling when
the mouse is moved outside of scrollable area. Checking the actual
length of selected text doesn't trigger this behaviour.
